| The GPIO controller will not report any new GPI interrupt as long as its interrupt status |
| register hasn't been read. |
| Reading the interrupt status register happens on a falling edge of the INT pin. |
| There seems to be a condition when the GPIO controller detects an interrupt but it's INT |
| pin stays high which masks any subsequent interrupts. |
| To avoid being stuck in that state, fire a timer to periodically check the interrupt status |
| register. |
